I <3 Humanity

You may think you're pretty good at online games, but you've got nothing compared to Sora. Of course, you're probably not a NEET (Not in Education, Employment, or Training) hikikomori (shut-in), so maybe you would be as good as Sora and his step-sister Shiro, if only you had their kind of time on your hands to practice gaming.

Wear a hoodie reminiscent of Sora's outfit, yellow on the chest with purple sleeves and hood. The familiar "I <3 humanity" Kanji can be found on the back (so that the full front zipper doesn't interrupt the design), and on the front you've got the No Game No Life logo and two pockets. And the aforementioned zipper. Probably won't improve your gaming skills, but hey, you never know. Handy to have on in case you do end up being summoned into Disboard.
